650nm 6mm 5V DC 5mW Mini Laser Dot Diode Module

Product Description

Add a precision pointing element to your builds with the 650nm 5V Mini Laser Dot Diode Module. This ultra-compact laser diode is designed for easy integration into low-power electronics and robotics. At Robogears, we recommend this module for its stable 5mW output, which provides a bright, clearly visible red dot even in well-lit indoor environments. Housed in a durable 6mm copper casing, it acts as its own heatsink for short-duration tasks. Whether you are building a laser-tripwire security system, a long-range optical communicator, or a laser-guided robot at your Pimpri facility, this 5V module offers a simple plug-and-play solution for your optical needs.

Detailed Key Features

• Compact 6mm Form Factor: The miniature cylindrical design allows it to be embedded into small enclosures, 3D-printed mounts, or even handheld devices.

• Low Power Consumption: Drawing less than 40mA, it can be powered directly from the 5V pin of an Arduino or Raspberry Pi without an external driver.

• Integrated Current Limiting: Features internal circuitry to protect the diode, though a series resistor can be added for extra safety during long-term continuous use.

• Focused Dot Beam: Emits a concentrated red beam with a 650nm wavelength, ideal for precise alignment and targeting applications.

• Industrial Copper Housing: The metal casing provides physical protection and basic thermal management for the sensitive laser diode.

All Technical Details

• Wiring: Typically comes with pre-soldered flexible leads (Red for +5V, Blue/Black for Ground).

• Visibility: Red dot is visible up to several dozen meters in low light (visibility depends on ambient light and atmospheric conditions).

• Mounting: Can be press-fitted into a 6mm hole or secured with a small set screw.

• Applications: DIY laser pointers, electronic security fences, target positioning, and light-beam sensors.
